mysql.cnf添加

[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8

 

drop database user;
CREATE DATABASE IF NOT EXISTS user character set utf8;

CREATE DATABASE IF NOT EXISTS user DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

create database youdb character set utf8;

show variables like "%char%";

character-set-server=utf8
collation-server=utf8_general_ci
[client]
default-character-set=utf8;

[mysql]
default-character-set=utf8
[client]
default-character-set=utf8
[mysqld]
character-set-server=utf8

 

 

 

 

1、通过rpm包安装的MySQL

service mysqld restart

/etc/inint.d/mysqld start

2、从源码包安装的MySQL

// linux关闭MySQL的命令

$mysql_dir/bin/mysqladmin -uroot -p shutdown

// linux启动MySQL的命令

$mysql_dir/bin/mysqld_safe &

其中mysql_dir为MySQL的安装目录，mysqladmin和mysqld_safe位于MySQL安装目录的bin目录下。

3、以上方法都无效的时候，可以通过强行命令：“killall mysqld”来关闭MySQL。
